This research aims to enhance the design and analysis methods for equivalence tests in randomized controlled trials.
Developed a statistical power formula for detecting equivalence with and without adjustments for covariates.
Created an optimal design framework to maximize statistical power within a fixed budget.
Implemented the proposed methods in the R package anomo.
Validated the new power formula against traditional methods, showing improvements in accuracy.
Presented an optimal sample allocation strategy that increases power without exceeding budget constraints.
Illustrated the application of these methods through examples.
